Optical switching dynamics of sub-micrometer Sb2Se3 thin films for active photonics
Optical switching dynamics of sub-micrometer Sb2Se3 thin films for active photonics
Optical Phase change material (O-PCM) components are rapidly becoming a mainstream implementation for non-volatile active control of photonic integrated circuits, metasurfaces and free-space photonics. In this work we explore the practical limitations of the reversible optical switching of the low-loss antimony-based O-PCM Sb2Se3 using a range of static tester and time-resolved techniques and demonstrates cyclability in Sb2Se3 beyond 10^6 reversible transitions. We demonstrate that optical pumping at 488nm results in a well-defined depth limit in the crystal to glass transition, which arises from the confinement of the nanosecond thermal excitation in the top region of the Sb2Se3 film.

Abstract
Optical Phase change material (O-PCM) components are rapidly becoming a mainstream implementation for non-volatile active control of photonic integrated circuits, metasurfaces and free-space photonics. In this work we explore the practical limitations of the reversible optical switching of the low-loss antimony-based O-PCM Sb2Se3 using a range of static tester and time-resolved techniques and demonstrates cyclability in Sb2Se3 beyond 10^6 reversible transitions. We demonstrate that optical pumping at 488nm results in a well-defined depth limit in the crystal to glass transition, which arises from the confinement of the nanosecond thermal excitation in the top region of the Sb2Se3 film.
